Estimation of the technical efficiency which measures the ability of a farm to obtain the maximum output from given input or to use the minimum input to achieve given output. This research used Stochastic Frontier Analysis, which was widely used in various fields. Based on the production cost of 'Wentan' pomelo in Report of Taiwan Agricultural Production Cost from 2010 to 2019, this research used Stochastic Frontier Analysis to explore the technical efficiency of 'Wentan' pomelo production and analyzed the influencing factors of pomelo business efficiency, and proposes to improve the technical inefficiency factor. The data were verified by the Translog production function in the stochastic frontier production function, and the results showed that labor costs, fertilizer costs and pesticide costs had an impact on production technical efficiency. Finally, this study has put forward suggestions for the production technology efficiency of 'Wentan' pomelo production to enhance the competitiveness of 'Wentan' pomelo production in Taiwan.
